The invention discloses a self-road-adaption hydraulic active suspension system. The self-road-adaption hydraulic active suspension system comprises a rigidity-variable and damping-variable drive suspension, a hydraulic system and a control system. The active suspension comprises a damping-variable shock absorber, a rigidity-variable spring and a hydraulic actuator. The control system comprises an electronic control unit and a plurality of sensors used for testing the state of an automobile. The suspension system can automatically control suspension rigidity and damping at the same time, and high running smoothness and control stability of the whole automobile are achieved; the control system is high in reaction speed; the height of the automobile can be regulated in a self-adaption or manual mode, and the whole automobile trafficability is improved; the structure and control strategies are simple, work is stable, and the service life is long; when the active suspension fails, the automobile performance is the same as the performance of a traditional passive suspension system, and the automobile can still normally run.
